Weather in September
Temperature
With the advent of September, Diarno's high-temperatures adjust to a still tropical 34.5°C (94.1°F), closely aligning with the preceding month. In Diarno, September nights cool down to an average of 26.4°C (79.5°F).Heat index
In September, the heat index is calculated to be a burning hot 47°C (116.6°F). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.Always consider that heat index estimations are for light winds and places in the shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly meaningful for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
